Abstract

The invention proposes a technique of preventing collision in a hospital environment by using a tactile sensor-flooring concept. The technique includes tactile sensor flooring, which addresses collision scenarios that include hospital equipment/staff and a robot. The tactile flooring detects presence of any object and tracks object motion. Tactile sensor flooring is used as a mat. The tactile flooring includes pressure sensors manufactured out of piezo-resistive polymer material spatially distributed over a surface. The tactile flooring detects presence of any object and tracks its motion. When the objects approach and cross the safety zone/limit, the system provides an alert via an alarm and potential collision is prevented.

TACTILE SENSOR FLOORING FOR VASCULAR CATHLAB

FIELD OF INVENTION

The invention generally relates to a hospital room environment with utilization of automated guided vehicle (AGV) robots and more particularly to a tactile sensor flooring to manage collision between moving robots in the hospital room environment.

BACKGROUND OF THE INVENTION

With recent developments in the field of medical appliances, mobile automated guided vehicle (AGV) robots have replaced catheterization laboratory (Cathlab). During interventional X-ray procedure utilizing mobile AGV robot, a patient lies in middle of interventional robots. However, while moving around patient or in room, the robot collides with hospital staff, people or equipment.

A conventional technique includes utilizing a pressure sensitive tube. The tube is used around an AGV base. However, the tube does not provide a reliable solution to prevent collision of robot within a hospital room environment. Also the tube covers a limited range of collision scenarios.

It would be desirable to have an efficient technique to manage collision between a moving robot AGV and hospital equipment or staff in the hospital room environment.
